COMPUTER SYSTEM EQUIPPED WITH BOOTING RESERVATION PART, AND BOOTING RESERVATION METHOD THEREOF

摘要

PURPOSE: A computer system and a booting reservation method thereof are provided to perform reserved booting out of an available maximum setting range without using a separate device such as a microcomputer on a clock module such as an RTC(Real Time Clock) that the available reservation time is restricted. CONSTITUTION: A power controller(3) supplies system power by controlling a power supply(2). The clock module(4) outputs a control signal to the power controller so as to supply the system power on a preset booting time having the available maximum setting range. A booting corrector(5) continuously advances the booting if a booting start time by supply of the system power is identical with a previously stored reference booting time, and interrupts the booting after resetting the reserved booting time if not. A booting reservation part(6) respectively stores the desired booting time to the clock module and the booting corrector as the reserved booting time and the reference booting time if the desired booting time inputted from a user is within the maximum setting range, and resets a wakeup time within the maximum setting range to the clock module as the reserved booting time if not.
